Time to update this one perhaps ?

10. What are the recommended system requirements for Band-in-a-Box?
Band-in-a-Box runs on Windows 98/ME/NT/2000/XP/Vista/7/8/8.1/10 (32bit or 64bit), and requires a minimum of 512MB available RAM. Basic MIDI features require a less powerful computer than the latest RealTracks features. For best performance, we recommend a fairly up-to-date computer with Windows XP or higher, a fast processor, and at least 2GB RAM. Without RealDrums or RealTracks, you need a minimum of about 1GB of free hard disk space (15GB recommended). More hard disk space is required for the RealTracks and RealDrums, roughly 100-400MB per Set. A full install of the PRO version (including RealTracks/Drums) requires about 15 GB. A full install of the MEGAPAK version requires about 25 GB. The UltraPAK is about 120 GB total, and you have the option of either downloading, or shipping "pre-installed" on a USB hard drive. You can run the program directly from the hard drive or install on your computer.

A MIDI sound source is required. This could be a sound card, a MIDI keyboard, MIDI sound module, or software synthesizer. We include a software synthesizer with Band-in-a-Box.[u][/u]
